A little uggly solution to include the "Excluded Files" and/or "Cookies" list is to just install Chrome at the side of Chromium and do a shortcut from "%LocalAppData%\Google\Chrome\User Data" to "%LocalAppData%\Chromium\User Data". That way CCleaner can be run normally for Chromium, which "User Data" directory it detects as Google Chrome's. But I'm not sure how Chrome and Chromium like the fact that they share the same settings.
As a side note I excluded "C:\Users\Det\AppData\Local\Chromium\User Data\Default\Cache\{data_0,data_1,data_2,data_3,index}" from the cache clean as those caches are some Chromium's own caches that get created even with a new Chromium profile with "about:blank" as the startup page.
